API viscosity is (almost) irrelevant to this question.
Refineries are able to vary the yield of different products considerably given their feedstock. The US uses a larger fraction of gasoline in its civilian economy. In any case the potential needs of diesel for military operations are always going to be a small fraction of civilian needs for ither oil products.
Your argument amounts to a quibble.
Well, I wasn’t talking military. I was talking food transportation. aka Trucks.
As to cut points you can vary yield of constituent parts varying cut point only if the temperature interface of the constituent parts is adjacent parts. It has no effect on gasoline production vs, say, asphalt.
There is no magic. If refineries could create desired constituent yields from all crudes, there would be no point in having an assay.
Like so:

Equinor’s assay page.
Select Bakken and anything with an API that is actual oil and not NGL, like Angola’s oil Girassol.
Have a look at the yields for temperature (cut) points.
Bakken is 30+% gasoline. 20% diesel.
Girrasol is 31% diesel and 20ish gasoline.
This matters. It’s not about pushing tanks around. It’s about tractors and trucks.
Apologies. I have seen Urals assay and I thought Statoil (Equinor) was the source but they don’t present Urals on their list, at least not anymore.
There are other assay pages. I think Exxon has one.
